Relationships among tone height, melodic contour, tone chroma, and recognition of recently learned melodies were investigated. Results replicated previous studies using familiar folk songs, providing evidence that melodic contour, tone chroma, and tone height contribute to recognition of both highly familiar and recently learned melodies.…

Research demonstrated successful discrimination in twenty 6-week-old infants when cardiac rate responses were employed in a no-delay rather than in the conventional discrete trials paradigm. (Author/SB)

Three experiments were undertaken involving three users of multi-electrode cochlear prostheses. The experiments established a scale of stimulus loudness; measured minimum-detectable gaps for sinusoidal stimuli as functions of stimulus level, frequency, and electrode place within the cochlea; and assessed independence of the electrodes using a…

Examined rate-based intersensory matching in infants by habituating them to concordant or discordant auditory-visual stimuli. Found a preference for the visual stimulus that moved at a novel velocity, indicating that the temporal attributes of the visual component dominated responsiveness. Found only limited evidence of intersensory matching. (WP)

Uses a nonsimultaneous pulsation threshold technique to examine the development of frequency resolutions in infants of three to six months. (PCB)

Investigated the effects of of distance on perception of unimodal visual speech and congruent and incongruent forms of the syllables /ba/, /bi/, /ga/, and /gi/. Identification of unimodal visual speech was unaffected by increasing distance to 10m, but was impaired at 20 and 30m. (Author/VWL)

In 2 experiments, 9- and 12-month-old infants were shown pictures of males and females with a female or male voice presented simultaneously. Found that infants spent more time looking at pictures of females presented with a female voice than at other stimuli pictures. (BC)

Assessed the relative contribution of dynamic and summary features of vocal frequency to the discrimination of pragmatic categories in infant-directed speech. Forty-nine mothers were instructed to use their voice to get their infant's attention, show approval, and provide comfort. Findings suggest that both dynamic and summary features are…

Although word stress has been hailed as a powerful speech-segmentation cue, the results of 5 cross-modal fragment priming experiments revealed limitations to stress-based segmentation. Specifically, the stress pattern of auditory primes failed to have any effect on the lexical decision latencies to related visual targets. A determining factor was…

Extinction of auditory fear conditioning is thought to form a new memory. We previously found that rats with vmPFC lesions could extinguish fear to the tone within a session, but showed no recall of extinction 24 h later. One interpretation is that the vmPFC is the sole storage site of extinction memory. However, it is also possible that lesioned…

This article describes a lesson plan model that applies principles of universal design for learning (UDL) and multisensory learning centers to the framework of a traditional direct instruction spelling lesson for elementary students with learning, social, and attention problems. It reviews essential components of UDL and demonstrates how to…

Purpose: To explore the sensitivity of children with specific language impairment (SLI) to amplitude-modulated and durational cues that are important for perceiving suprasegmental speech rhythm and stress patterns. Method: Sixty-three children between 7 and 11 years of age were tested, 21 of whom had a diagnosis of SLI, 21 of whom were matched for…

Purpose: To examine the influence of visual information on speech intelligibility for a group of speakers with dysarthria associated with Parkinson's disease. Method: Eight speakers with Parkinson's disease and dysarthria were recorded while they read sentences. Speakers performed a concurrent manual task to facilitate typical speech production.…

This study examined how three different sources of stimulus variability--overall amplitude, fundamental frequency, and speaking rate--affect second language (L2) vocabulary learning. Native English speakers learned Spanish words in presentation formats with no variability, moderate variability, and high variability. Dependent measures were…

The auditory event-related potential (ERP) is obtained by averaging electrical impulses recorded from the scalp in response to repeated stimuli. Previous work has shown large differences between children, adolescents and adults in the late auditory ERP, raising the possibility that analysis of waveform shape might be useful as an index of brain…
